Silk fibroin coated antimicrobial textile medical products

In this study an attempt has been made to develop eco-friendly natural fibre based medical products such as baby’s diaper, sanitary napkins and surgical wound dressings. These products were developed by coating natural silk fibroin protein extracted from natural silk fibre. An effective technique has been used for extraction of silk fibroin protein from raw silk by successive methods of degumming, dissolution and dialysis. In addition, the silk fibroin protein was combined with certain natural oils such as neem, clove, eucalyptus which were found to possess anti-microbial property. This protein/oil mixture in the ratio of 10:1 was applied to impart anti-microbial property to the products.Medical products incorporating natural fibres like organic cotton, sterilized cotton and bamboo coated with the natural silk fibroin protein and natural anti-microbial oils demonstrate excellent holding capacity, wicking behaviour compared to commercially available products. All the products exhibit very good anti-microbial property which is needed for the medical product.
